To all whom it may concern Be it known that I, WILHELM ROTI-IE, a subject of the German Empire, residing at Reichenbach, Silesia, Prussia, Germany,

have invented a certain new and useful Im-xy provement in and Relating to Apparatus for Obtaining Cotton-Waste in a Rope- Like Form; and I declare the following to be a full, clear, and exact description of the ton Waste in a rope-like form and pertain ing particularly to a device for transforming the fleece running off of a carding machine into a small rope, the fleece being arranged and laidby guide ridges as hereinafter described andclaimed.

In the accompanying drawing Figure 1 is an elevation and Fig. 2 a plan view ofthe entire apparatus represented diagrammatically. Fig. 3 is aplan'view of the. part of the apparatus in enlarged scale, by which the fleece. is formed or rolled into a small rope, and Fig. 1 is a longitudinal section of the device shown in Fig. 3. i

There exists a peculiarity in connection with carding machines for obtaining cotton waste, which rests inythe fact that in preparing the fleece the lower side of the bat is the smoother and more finished side, the upper side of the ,fleece as moved through the machine representing that portion which laid against the surface of the dotfer-cylinder between'the prongs and so presents a surface not so smooth and sightly as the normal top surface. 'In order to utilize this feature to the fullest eX- tent, in the formation of a rope, having the highest degree of sightly and compact teX-, ture, it is necessary to roll in equally from each edge the fleece as it runs off the ma chine in such a manner that the more evenly laid side forms the outside of the future rope, The above purpose is effected preferably by a guidesurface or *folding device to which the fleece obtained from a carding machine or the like is fed. This guide surface or folding device, according to the ap plication filed Jan. 5, 1912, Serial No.

669,625, is ribbed longitudinally in order to impart to the fleece a guiding influence.

Specification of Letters latent.

In the present invention;theYguide-sun face is structurally improved as shown particularly in Figs. 3 and 4;.

The folding device consists of sheet v or any other suitable metal, rolled and tapered at oneend'to form a drawingtrunr pet and being provided with downwardly bent fins or blades (1 and laterally arranged resilient members or guides CF. The number of these guide-ribs or fins variesac cording to the quality of the 'materialemployed. The drawing trumpet isconnected to the dofling cylinder 0, as is evident in 3 through the trumpet by guiding rollers e. 1 I

transversely of its movement, so that it willv i be rolled inwardly from its side edges without folds. The guide ribs cut into the fleece being drawn thereover and preserve its flattened condition in the middle portion of the trumpet so that longitudinal folds.

cannot be formed, while the fleece bat is gradually narrowed in its progress through the drawing trumpet. As the fleece is drawn through the trumpet blades "or fins (Z in combination with the turned-in edges- 5 hers d cause both sides of the fleeceto' roll a in more and more until the machine-wide of "the trumpet and with the resilient mem fl'eecerunning off of the carding cylinder is a H contracted into the desired width [from which the rope is drilled. The said rolling-in operation is aided by the transversely extending. resilient members. alover which the partly rolled-in materialisdrawn by thew rollers e. The side portions of the fleece are laid thereby in the middle portion of the fleece by directing the rolling-in operation so that the lower of the members (Z acting as abacking or support to the fleece as it is turned over by the trumpet. 1 a i a indicates the taking-off cylinder in a type of'carding machine which is provided with prongs (notshown), saidcylinder a taking the fleece from the drum or cylinder smoothside of the fleece always comes outside, the resiliency.

WhatIclaim is 1. An apparatusfor transforming a fleece intoa rope-likeform, comprising a trumpetshaped guide surface having. its edges 1' formed to turn the edges of the fleece i11 of substantially lonsurface While the edges of the latter roll the edges of the fleece inwardly.

2. An apparatus for transforming a fleece into a rope-like form, comprising a trumpetshaped guide surface, having in-turned edges for rolling the fleece, substantially longitudinal fins projecting upwardly from provided within saidtrumpetthe bottom of said guide surface to hold the fleece in spread relation in the middle portion of the guide-surface and resilient members for supporting and directing the rolling of the edge portions of the fleece.

In testimony whereof I affix my signature in presence of two Witnesses.
